New WinMM code for FlashWaveOut

[ydario]

New DART implementation for better Flash audio playback.

[rlwalsh]

Committed as revision 21358.

FlashWaveOut is an alternative to DartWaveOut that is less likely to cause "looping" (repeatedly playing the last quarter-second of sound when a buffer underrun occurs). To use it, an app should #include "flashaudio.h" and call ODIN_EnableFlashAudio(TRUE).

An odin.ini entry is also available ("FlashAudio=0" or "FlashAudio=1") but under normal circumstances, it should not be present in odin.ini. It is intended for users who need to force FlashWaveOut to be disabled or enabled, and overrides calls to ODIN_EnableFlashAudio().

This patch also restructures & refactors all of the Wave classes. It gives each an ::open() method, relocates class data members to the classes that actually use them, and generally tightens-up the code.

shouldn't this be closed, as the code is in since long?

Checked, all is there indeed. Closing.
